Commercial and Multi-Family Energy Efficiency Requirements

Option #1 - The Residential prescriptive requirements are found in Chapter 4 of the 2009 International Energy Conservation Code;

The Commercial prescriptive requirements are found in Chapter 5 of the 2009 International Energy Conservation Code.
